Carbon instensity of Sustainable PV for Energy Transition¶

This analysis explores the carbon implications of different PV sustainability/circular economy designs in the context of achieving energy transition. These calculations build upon previous work that can be found in journals 13 and 17.

Project grid forward to 100% re in 2050¶

To parallel the PV deployment, we will assume that we globally hit 100% RE in 2050 with the 75 TW of PV. As such, we need to change the future projection of marketshares of the different country grids.

One scenario with decarb grid, one scenario with decarb grid and heat

Estimating that 60-70% generation will be from Solar, 30-40% from wind, and any remainder from "other renewables"

This is a simple projection, assumes all countries have same ratio of PV and wind (which we know can't be true). Update in future with country specific projections.

Flip it, compare on CO2eq/kWp¶

This is a simple way of doing it, will not work for much beyond 2022, because the annual emissions include end of life of other systems, not just the mfging of installed - its not necessarily fair. Might work out on balance, kinda

Emissions per Capacity¶

Trying to quantify the emissions entailed in achieving energy transition target capacities. Our current calculations don't allow a good method of CO2/kWh, but we do know how much it now takes to achieve the first 75 TW then the the next 11 TW will entail a different amount of carbon. This may be a valuable comparison
